'Mark Kendall and his colleagues have shown they are able to coat nanopatch microprojections with a vaccine, apply the nanopatch to the skin and achieve vaccination with one tenth to one thirtieth of the dose required using traditional needle and syringe approaches.
Is it worth all this effort to find an alternative? (to a needle - Neil)
Actually yes. At least 10% of the population has needle phobia, and actively avoid being vaccinated by needles.
Furthermore, the World Health Organisation estimates there are 1.3 million deaths which occur each year from needlestick injuries and cross contamination.
The future of this technology looks bright not only for vaccine delivery, but also for other diseases and injuries where targeting the body’s immune cells is an important component of treatment. Examples include influenza, cholera, polio and rabies.'
